My wife and I have argued this, and I've had trouble finding the answer. Which sex carries the genes to determine the sex of the offspring The sex of a human baby is determined by the composition of its sex chromosomes a single distinct pair among humans' 23 pairs of chromosomes. Females possess two copies of the same chromosome referred to as the 'X' chromosome ; males have one copy of the X chromosome and one copy of the smaller, hook-shaped Y chromosome. When fertilization occurs, the new gamete the initial cell from which a fetus grows always inherits one of the mother's X chromosomes, and either a X or a Y from the father, depending on which chromosome the fertilizing sperm cell happened to inherit. One could say, then, that the father-or, at least, his sperm-determines the sex of the child.

In humans, What determines the sex of the offspring?

I am thankful for this very simple affirmation of simple science as I had remembered from college biology; however, I have just read an article from a university in Missouri that is attributing the sex of a lamb produced to the type or quality of feed given to ewes. It has me perplexed. I understand that the ovulation of the ewe could be affected by feed quality, that's why people practice fushing, but I can't see where it could have any other bearing.

The male generally gets the sex of offspring that he longs for. It IS odd, but the male determines the offsprings' sex. In humans, which sex chromosome determines if an offspring is a male or female? The temperature at which the eggs are incubated influences the sex of the offspring.
